Crestliner Fish Hawk 1850 Tiller 2006 vs Crestliner Sportfish 1750 O/B 2005 — Same Brand, Different Boat

The Crestliner Fish Hawk 1850 Tiller 2006 vs Crestliner Sportfish 1750 O/B 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Crestliner Fish Hawk 1850 Tiller 2006 at 18,0 ft versus Crestliner Sportfish 1750 O/B 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Crestliner Fish Hawk 1850 Tiller 2006 tips the scales at 125 lbs — 112 lbs more than the Crestliner Sportfish 1750 O/B 2005 at 13 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 140 hp, the Crestliner Sportfish 1750 O/B 2005 has a 50-hp advantage over the Crestliner Fish Hawk 1850 Tiller 2006's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 31 gal and 33 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Sportfish 1750 O/B 2005 comes in at 0 lbs per hp versus 1 lbs per hp for the Crestliner Fish Hawk 1850 Tiller 2006. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the Crestliner Sportfish 1750 O/B 2005 and its 140-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner Fish Hawk 1850 Tiller 2006 with its 90-hp rating is the more economical daily driver.
